CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to Chinese Patent Application No. 201410531217.5, filed on Oct. 10, 2014, which is herein incorporated by reference in its entirety.

TECHNICAL FIELD

The present application relates to a field of display technologies, in particular, to a pixel structure, a manufacturing method of a pixel structure, an array substrate, and a display panel.

BACKGROUND

With the development of display technologies, Liquid Crystal Display (LCD) devices have been widely used, and the display effect of the LCD devices is improved continuously.

A pixel structure located on a Thin Film Transistor (TFT) array substrate is an important part of the LCD device. Different pixel structures enable the LCD device to have different display effects. FIG. 1 is a schematic structure diagram of a pixel structure in the related art. As shown in FIG. 1, in the related art, the pixel structure of the LCD device includes a plurality of data lines 11, a plurality of scan lines 12, a plurality of pixel units 13 formed by intersecting the plurality of data lines 11 with the plurality of scan lines 12, and a TFT 14 and a pixel electrode 15 located in each of the pixel units 13. Each of the pixel electrodes 15 includes a plurality of slits 151, and each of the slits 151 includes two ends (a upper end and lower end of the slit in FIG. 1) both having a corner A1. Additionally, an area A2 is the area covered by a black matrix on a color filter substrate in correctly adhering the color filter substrate onto a TFT array substrate.

It can be seen from FIG. 1, the black matrix covers a part of the corner A1 of the slits 151 and the remaining part of the corner A1 is located in an open area in the case of correctly adhering the color filter substrate onto the TFT array substrate. In at least some instances, more parts of the corner A1 are located in the open area in the case of deviating the color filter substrate from the TFT array substrate in adhering. The electric field formed by the corner A1 of the slits 151 is different on controlling the direction of the liquid crystal molecules from the electric field formed by the remaining part of the slits 151 other than the corner A1, where the electric field formed by the corner A1 of the slits 151 will cause a reduced light transmittance as compared to the electric filed formed by the remaining part other than the corner A1 of the slits 151 in displaying of the liquid crystal display device. In addition, if more parts of the corner A1 of the slits 151 are located in the open area, a risk of a trace mura of the image displayed on the LCD device would also be increased.

DETAILED DESCRIPTION

The present disclosure will be further illustrated in detail below in conjunction with the accompanying drawings and embodiments. It may be understood that specific embodiments described herein are merely for explaining the disclosure rather than limiting the disclosure. Additionally, it is noted that merely partial contents associated with the disclosure rather than all contents are illustrated in the accompanying drawings for ease of description.

Embodiment of the disclosure provide a pixel structure. FIG. 2 is a schematic diagram of the structure of a pixel structure according to embodiments described in the disclosure. The pixel structure includes a plurality of data lines 21, a plurality of scan lines 22, and a plurality of pixel units 23 formed by intersecting the plurality of data lines 21 with the plurality of scan lines 22, where each of the pixel units 23 corresponds to one of the plurality of data lines 21 and one of the plurality of scan lines 21; and each of the pixel units 23 includes a pixel electrode 25 and a thin film transistor 24 therein. The pixel electrode 25 includes a plurality of slits 251, with at least one of the plurality of slits 251 having a corner B1. In a column of pixel units 23, the pixel electrode 25 of each pixel unit 23 in a row is electrically connected to the thin film transistor 24 of the pixel unit 23 in a preceding adjacent row, and the corner B1 of the pixel electrode 25 close to the thin film transistor 24 extends toward the thin film transistor 24.

It should be noted that the pixel electrode of the pixel unit and the thin film transistor electrically connected with and configured for controlling the pixel electrode are used for implementing the display of the pixel unit. The thin film transistor controls the pixel electrode, and hence the thin film transistor controls the pixel unit including the pixel electrode. The scan line electrically connected with the gate electrode of the thin film transistor can turn on or turn off the thin film transistor. The data line electrically connect with the source electrode of the thin film transistor, and the data line can provide a data signal for the pixel electrode electrically connected with the thin film transistor, when the thin film transistor is turned on. Based on this, each of the above pixel units 23 corresponds to one of the data lines 21 and one of the scan lines 22. Namely, the data line 21 corresponding to the pixel unit 23 is the one electrically connected with the thin film transistor 24 for controlling the pixel unit 23; and the scan line 22 corresponding to the pixel unit 23 is the one electrically connected with the thin film transistor 24 for controlling the pixel unit 23.

In a column of pixel units, the pixel electrode 25 of each pixel unit 23 in a row is electrically connected to a thin film transistor 24 of the pixel unit 23 in the preceding adjacent row, and the corner B1 of the pixel electrode 25 close to the thin film transistor 24 extends toward said thin film transistor 24, and thus the corner B1 close to the thin film transistor 24 can be completely covered by the black matrix in the color filter substrate after the color filter substrate is adhered to the array substrate. With such pixel structure, the number of the corners of the pixel electrode in the open area is reduced, and accordingly, the light transmittance is improved and a risk of a trace mura of the image displayed on the LCD device is decreased, as compared with the related art.

In the pixel structure as shown in FIG. 2, the pixel units are arranged as a matrix. In addition, the pixel units can alternatively be arranged in a staggered way. Namely, in a column of pixel units, each pixel unit in a row is staggered to one side from a pixel unit in an adjacent row by a half width of pixel unit. The pixel structure in FIG. 3 is different from the pixel structure in FIG. 2 in that, the pixel electrode 25 of the pixel unit 23 in a row is electrically connected to the thin film transistor 24 of the pixel unit in a preceding adjacent row of the pixel electrode 25 of the pixel unit 23, and the thin film transistor 24 of the pixel unit in a preceding adjacent row is located at left side of the pixel electrode 25 of the pixel unit 23 in the row, and the corner B1 of the pixel electrode 25 close to the thin film transistor 24 extends toward the thin film transistor 24. Additionally, an area B2 in FIG. 3A is the area covered by a black matrix on a color filter substrate which is correctly adhered onto a TFT array substrate.

Referring to FIG. 3A, the corner B1 above the pixel electrode 25 bends toward the thin film transistor 24 electrically connected to said pixel electrode 25. As such, the corner B1 can even more extend toward the corresponding thin film transistor 24, allowing the corner B1 to be better covered by the black matrix of the color filter substrate.

FIG. 3A is an example of the pixel structure formed by arranging the pixel units in the staggered way. In another example, the pixel structure of FIG. 3B is different from the pixel structure of FIG. 3A in that, a pixel electrode 25 of each pixel unit 23 is electrically connected to a thin film transistor 24 of a pixel unit 23 in a preceding adjacent row of the pixel electrode 25, and the thin film transistor 24 of the pixel unit in a preceding adjacent row is located at right side of the pixel electrode 25 of the pixel unit 23 in the row, and the corner B2 of the pixel electrode 25 close to the thin film transistor 24 extends toward the thin film transistor 24. In FIG. 3B, similarly, the corner B1 above the pixel electrode 25 bends toward the thin film transistor 24 electrically connected to said pixel electrode 25.

Based on the pixel structure described above, a pixel structure in embodiments of the disclosure further includes a common electrode 26, as shown in FIG. 4. The common electrode 26 is located between the pixel electrode 25 and a film layer, the film layer includes a source electrode 242 and a drain electrode 243 of the thin film transistor 24 electrically connected with the pixel electrode 25, and the common electrode 26 is electrically insulated from the pixel electrode 25 via a third insulating layer 273 and is electrically insulated from the source electrode 242 and the drain electrode 243 via a second insulating layer 272. Additionally, as shown in FIG. 4, the gate electrode 241 is covered by a first insulating layer 271; an active layer 244 is located on the first insulating layer 271; the source electrode 242 and drain electrode 243 are separately arranged on two lateral sides of the active layer 244 and electrically connected to the active layer 244; the source electrode 242, the drain electrode 243, and the active layer 244 are insulated from the gate electrode 241 via the first insulating layer 271, and the drain electrode 243 is electrically connected to the pixel electrode 253.

Because the pixel electrode 25 overlaps with the scan line 24 corresponding to the thin film transistor 24 electrically connected with the pixel electrode 25, affection on electric signal might be generated at the overlapped area during working. Therefore, the common electrode 26 is located between the pixel electrode 25 and the source electrode 242 and the drain electrode 243 of the thin film transistor 24 can have a function of shielding the electric signal at the overlapped area between the pixel electrode 25 and the scan line 22.

It should be noted that, the arrangement of the gate electrode 241 of the thin film transistor 24 as shown in FIG. 4 where the gate electrode 241 is arranged below the source electrode 242 and drain electrode 243 is just one example. In other examples, the gate electrode 241 can alternatively be arranged above the source electrode 242 and drain electrode 243, which is not limited thereto.

In embodiments of the disclosure, further in a column of pixel units, a corner of a pixel electrode of each pixel unit in a row, which is close to a thin film transistor of a pixel unit in a preceding adjacent row, overlaps and is insulated from the scan line configured for controlling the thin film transistor. For example, in the pixel structures of FIGS. 5A to 5C corresponding to the pixel structures of FIG. 2, FIGS. 3A, and 3B, respectively, a corner B1 above the electrode 25 overlaps with and is insulated from the scan line 22 corresponding to the thin film transistor 24 electrically connected with the pixel electrode 25. The corner B1 extends towards the thin film transistor electrically connected with the pixel electrode 25 including the corner B1 and overlaps with the scan line 22 configured for controlling the thin film transistor 24, so that the corner B1 can be better covered by the black matrix of the color filter substrate, and hence the corner B1 can be completely covered by the black matrix in a light transmitting direction, thereby improving light transmittance of the pixel structure as well as decreasing a risk of a trace mura of the displayed image.

In embodiments of the disclosure, the pixel electrode is finger shaped optionally. As shown in FIG. 6A, the pixel electrode 25 is finger shaped. One end of the slit 251 of the pixel electrode 25 (an upper end of the slit 251 in FIG. 6A) has the corner B1, the other end of the slit 251 (a lower end of the slit 251 in FIG. 6A) has no corner B1. An end of the pixel electrode 25 which has the corner B1 is electrically connected with the thin film transistor 24 of the pixel unit 23 in a preceding row and adjacent to a pixel unit 23 including the pixel electrode 25. The corner B1 extends towards the thin film transistor 24, so that the corner B1 can be completely covered by the black matrix of the color filter substrate without location of the corner B1 in the opening area, thereby further improving light transmittance of the pixel structure as well as decreasing a risk of a trace mura of the displayed image.

It should be noted that, in addition to the above structures of the pixel electrode, the structure of the pixel electrode can also be designed in other manners. For example, as shown in FIG. 6B, two ends of the slits 251 of the pixel electrode 25 each have a corner B1 which bends towards the same side, such as a right side. Alternatively, as shown in FIG. 6C, two ends of the slits 251 of the pixel electrode 25 each have a corner B1 which bends towards the right side, and in addition, the slits in FIG. 6C is different from that in FIG. 6B in that it further includes a V shaped structure so that a double domain structure of the pixel electrode 25 is formed.

In embodiments of the disclosure, the source electrode of the thin film transistor is electrically connected to the data line corresponding to the pixel unit including the thin film transistor; and the gate electrode of the thin film transistor is electrically connected to the scan line corresponding to the pixel unit including the thin film transistor. With such electrical connections for the thin film transistor, in a column of pixel units, a pixel electrode of each pixel unit in a row is electrically connected to a thin film transistor of a pixel unit in a preceding adjacent row.

In embodiments of the disclosure, a distance between a pixel electrode and a pixel electrode of a pixel unit including the thin film transistor electrically connected with the pixel electrode is greater than or equal to 4 μm and less than or equal to 6 μm. By setting the distance between a pixel electrode and a pixel electrode of a pixel unit including the thin film transistor electrically connected with said pixel electrode in such a range from 4 μm to 6 μm, the number of the corners in the opening area can be reduced while avoiding interference of the field signals between a pixel electrode and a pixel electrode of a pixel unit including the thin film transistor electrically connected with said pixel electrode.

FIG. 7 is a schematic flowchart of a manufacturing method of the pixel structure according to embodiments described in the disclosure.

In Step 302, a plurality of data lines and a plurality of scan lines are formed, where a plurality of pixel units are formed by intersecting the plurality of data lines with the plurality of scan lines, and each of the pixel units includes a thin film transistor.
